Background: The ultrasound B-scan is one of the most commonly used ophthalmic investigations in day-to-day practice. It is a noninvasive investigative modality to assess the posterior segment of the eye and is irreplaceable in patients with hazy or opaque media. Purpose: This video aims to summarize a few tips for beginners to help them perform and interpret a B-scan with ease. Synopsis: In this video, we have briefly described the principle of B-scan using animations. The various scanning techniques and probe orientations have been demonstrated using short video clips. We have also summed up the indications and how various clinical entities appear in a B-scan. Highlights: The teaching points include the principle, indications, probe orientations, and how common retinal pathologies appear in a B-scan. Video link: https://youtu.be/lUlUvShIy9A.
